Riello 220 → 240V Input Tower Uninterruptible Power Supply, 6000VA (6kW), Extended recharger for Sentinel Tower

The Riello STW 6000 ER series is the Sentinel Tower is the ideal solution for protecting mission-critical systems such as safety devices, telecommunications equipment but also IT systems to ensure maximum power reliability. Sentinel Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings. The series includes 5-6 kVA single/single-phase and 8-10 kVA single/three-phase input single-phase output models with ON LINE double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency. In terms of technology and performance, Sentinel Tower is one of the best UPS available on the market today: three-level inverter to achieve 95% efficiency, output power factor 1 to increase in efficiency of system and devices and reduce power system losses.

High efficiency 95%
Parallel able up to 3 units
3 level inverter
High quality output voltage

ER series models have no internal batteries. These versions are fitted with upgraded battery chargers, for long runtime and business continuity applications. The batteries are housed in separate cabinets.
